If you’re looking for authentic gold jewellery, recent prices may have shocked you. In September 2026 alone, the price of pure gold rose by 12.2%, while global prices climbed 128% over five years. Against that backdrop, a designer or high-street piece with a surprisingly low price can feel like a rare find. Look closer, though, and it’s often labelled “gold tone” or “gold plated.” These pieces can still be beautiful. However, they differ from real gold jewellery in composition, durability, and quality of craftsmanship.
Knowing the difference between the two and which marks to check for authenticity will help you judge what you’re buying and spend with confidence.
Gold tone jewellery has a gold-coloured finish, but the term doesn’t promise any real gold content. Makers usually colour a base metal such as brass with paint or a wax finish. By contrast, “gold plated” indicates a thin layer of gold over another metal. While real gold is in the plating, it’s often low karat and the coating can wear away over time.
Gold tone jewellery is a great option for trend-led pieces because it costs significantly less. However, friction, water, perfume, and sweat can all tarnish the piece and expose the actual metal beneath. Always check the product description for the base metal used and care guidance, especially if your skin reacts to certain materials.
Real gold jewellery contains gold throughout the metal, rather than just on the surface. Because pure gold (24 karat) is so soft, most jewellery pieces use an alloy, meaning gold mixed with metals such as silver, copper, or palladium. The blend helps jewellery hold its shape during normal use. It can also create rose or white gold.
A craftsperson starts with refined gold and calculates the metals needed for the chosen purity and colour. The maker usually sources the refined gold by buying gold bars from a reputable broker. Then, they melt the pure bars with other metals to create an alloy and cast it into a mould. The jewellery maker then shapes, joins, and polishes the jewellery parts before setting stones and sending eligible UK pieces for hallmarking. In large-scale gold jewellery production, manufacturers use computer modelling and precision casting instead.
Gold trades as a valuable global commodity, so purity and weight drive much of the price. Increasingly, you’ll find lower purity pieces on the market, as alloyed gold jewellery costs less to source materials for and produce. An 18-carat piece contains 75% gold, while a 9-carat equivalent contains 37.5%; at the same weight, the first contains twice the gold.
Gold resists rust and tarnish and, because it’s soft, jewellers can shape fine detail more easily than many other metals. However, the softness also makes it prone to scratching and misshaping. Gold’s purity also influences its visual lustre: higher-carat gold usually has a richer yellow colour. Lower-carat alloys are more resilient to wear and tear, so 9-carat or 14-carat gold is practical for an everyday ring you’ll wear regularly.
How can I tell if a piece of jewellery is real gold?
Understanding hallmarks and carats
Start by examining the inside of a ring, the back of a pendant or the clasp on a chain with a magnifying glass. In the UK, one of four government regulated Assay offices mark all precious metals to protect against fraud. A complete UK hallmark normally includes a sponsor’s mark, a fineness mark, and an Assay Office mark. The fineness number states gold content in parts per thousand:
UK law requires items sold as gold and weighing more than one gram to carry a recognised hallmark. If the marks look unclear or the price seems unusually low, ask an Assay Office-registered jeweller to evaluate the piece and provide written details before you buy.
Yes. Jewellers make 24-carat or 999-fineness pieces, and buyers value their deep colour and high gold content. As pure gold remains soft, it just changes how you should wear and store it. Pure gold works especially well for ceremonial jewellery or occasion pieces you’ll wear rarely and with care.
